6 Stages of the Mining Process BOSS Magazine

Jun 22, 2018 The mining process can be broken down into two categories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Underground mining. The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges

Silica Minerals Education Coalition

Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics.

Silicon dioxide Wikipedia

Silicon dioxide is mostly obtained by mining, including sand mining and purification of quartz. Quartz is suitable for many purposes, while chemical processing is required to make a purer or otherwise more suitable (e.g. more reactive or fine-grained) product.
